The retractable cord reels also include a flat electrical cable having a first portion disposed in the expansion chamber, a second portion disposed in the inner channel, and a third portion disposed in the passage to follow a path from the outer surface of the spool to the inner channel.

Description

Ϊ 251577 玖, DESCRIPTION OF THE INVENTION: FIELD OF THE INVENTION The present disclosure is generally related to retractable reels, and more particularly to retractable reels for use with flat cables. [Prior Art] Retractable reelers are commonly used in many different applications involving a wide range of environmental conditions, electrical signal types and numbers, and expected or required extended/shortened lifetimes. For example, the retractable reel can be used, for example, in a hazardous environment in which the reel is exposed to explosive gases, combustible fluids, etc., which can be used, for example, in maritime humid environments or other outdoor environments. In the environment, it can be used to expose the cord reel to TQ NAME A FEW in an environment such as dust, corrosive gases, oils and the like. In addition, some reels are used in applications involving a relatively large number of low power nicknames, such as in telephony applications, data transfer applications, and the like. Many of these low power applications subject the reel to an expansion/contraction cycle of Aida. Other reel applications involve a relatively small amount of high power signals, such as linear voltage expansion reel applications. In any event, conventional retractable reel devices typically include a fixed portion of the cable and an extendable portion of the cable. The extendable portion of the cable is often stalked on a spring loaded reel and thus may be pulled back or extended from the reel and, if desired, it can be retracted into the reel. When the extendable cable portion is pulled back, it typically rotates the spool against the force of the spring. The energy stored in the spring may then be used to rotate the spool in the opposite direction Ϊ 251577 to retract the extendable cable portion into the cord reel. Of course, providing a continuous electrical connection between the fixed and extendable cable sections is not a simple matter, especially because of the relative rotation between the fixed electrical section and the spool carrying the extendable cable section. Some known retractable reels utilize rotational contact, such as brush = and rectifying rings, to provide electrical continuity between the fixed cable portion and the rotating reel that is wrapped with extendable power. Through these types of coiling, the extendable winding portion is often electrically connected to the integral ring that is integral with the rotating spool, and the fixed cable portion is electrically connected to the brush that is secured to the cord reel housing. And was forced to resist the rectifier ring. Unfortunately, such moving or rotating contact systems are subject to wear and thereby significantly reduce the life cycle of the cord reel. Moreover, these moving or rotating contact systems have a tendency to generate sparks which are not compatible with X in hazardous environments and are susceptible to contamination by dust, liquids, etc., which are ubiquitous in many reel applications. Furthermore, the rotating or moving contact is electrically inhomogeneous and difficult to protect from the environment, so it is generally unsuitable for carrying low power, low standard signals. : Nearly some of the reelers have been developed, which are privately required for mobile 4-turn contact. These reelers utilize a substantially continuous electron microscope having a flat portion of a flat portion. The rounded portion of the electric iron, A-rotatable coiling, and the flat portion that is electrically wound is spirally wound around the expansion chamber adjacent to the reel hub to be pulled back from the reel Or when retracted, the flat (four) portion of the snail is first unfolded or expanded, and then wound around the reel 1251577

U.S. Patent No. v - has a reel including a 可 round extendable portion and a flat fixed portion / knife substantially continuous cable has been proven to include examples and telephone signals, signing 1 Many different applications of applications such as 咕一^, ear g signals, tributary signals, etc.: The use of cables used in such devices is typically quite complex and expensive. Furthermore, although the cable types used in many low power applications as described above can be formed to have a comparable flat portion and a comparable rounded portion connected along one of the cables; length, for example, reloading standard Many of the power of the power system is difficult = the modification of this method (if the modification is not impossible) ^ Again, due to safety requirements, many reloading standard flat cables use a relatively thick and sturdy cover Or the insulating member H may be re-installed as a fixed part of the standard electrical system, which may cause premature failure, because it is roughly one hundred and eighty degrees when it is converted between the retracting and expanding modes in the expansion chamber. After the bending cycle, the bending stress is typically concentrated at one of the cables or regions. ... [Summary of the Invention]

It is an object of the present invention to provide a retractable reel comprising: a housing portion; a reel disposed within the housing portion and having an expansion in one of the housing portions The outer surface associated with the chamber, 1251577, is configured to maintain a shot: a strong $ τ, an inner passage that retains one of the lengths of the flat cable, and an extension Γ Ah between the outer surface and the inner passage And the flat sale* "Tube, Gan ^, /, Department 8 has a part of the younger brother who is placed in the expansion chamber, a second part of the 远 gu iii + i placed in the far inner channel, and A third portion disposed in the passageway for following a path from the outer side surface of the spool to the inner passage. [Embodiment] The brother-picture is an exemplary reeler's solution for use with a flat electric environment.

The fixing member 1 p A 1 ^ ,,. Can be threaded, ^ am _ wire or bolt. Alternatively or extra splitting Ί Ί Ί /1 γ above and below the outer shell knife 1 2 and 14 can use pressing and adhesive, ultrasonic 煜The lord/secondary splicing features are combined with the singularity and any other suitable fixing technique: the two-axis ι8 system is placed in the reel 1 〇 衔 一个 毂 毂 2 2 2 2 2 2 2 2 Outside"... its reading, the valley 2 is the same as the one below the outer one's volume Straight in the remnant section 2 〇 18, an expansion chamber or cavity is formed between the reel 18 and the surface of a surface 24 of the lower outer casing portion 14 as will be referred to hereinafter. The three figures and the fourth figure are more detailed;

An electric winding is wound around one of the reels 18; a portion of the surface of the main I yM is expanded and retracted within the expansion chamber 22 as a retractable portion of the money, It is wound around a channel 26 of the winding magazine 8 and is pulled back or retracted from the cord reel 10 into the reel i 亦. The lower outer casing portion 14 also includes a passage 28 And an opening 3 〇 configured to enable the flat electric gauge to pass from the expansion chamber 22 to exit the reel i 〇. An outlet bushing or buckle "..." can be placed on the opposite side of the opening 30 to provide strain relief to a portion of the cord reel that exits the cord reel. The outlet liner 3 2 A3 4 can be made of an elastomeric material, such as rubber, thermoplastic, or any other suitable material. It is said that the 'Shaft Outlet Bushings 3 2 and 3 4 are configured to grasp—reload the standard flat electric cover. The outlet bushings 3 2 and 3 4 are optional, and the sub-system may be in a condition that is not required for strain relief or is not desired by the person and/or is released in strain as one or more other via the reel The feature is either eliminated via the conditions provided by a mechanism external to the reel i. The lower outer casing portion 14 also includes another opening 36, and a retractable portion of the cable wound in the passage 26 of the reel 18 is passed through the opening 36 to exit the reel. Hey. A sleeve or bushing 3 8 4 is placed over the individual legs 4 2 and 4 4 on opposite sides of the opening 36.
